I'm really reluctant to answer back for MP, but: So what? There is nothing saying it has to be this way.

And if you look closely, the EHLO name resolves to just the client's source IP address, which is not even necessary for compliance, but should really be sufficient if you have such tests. > BUT, from my perspective, as a "junkemailfilter", the DNS should be perfect I will not comment on this... -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
